A) 56% paid by top 4 countries. Remaining share of 2 of the top 6 = 11.8%.
Doesn't talk about country X at all. Insufficient.

B) If country X is in top 6 (and worst case, 6th), other countries would have paid at least a little more than it. 4.8*6 = 28.8 is much less than 67.8% of the top 6 countries. At the same time, if the top countries in top 6 have paid much more than 4.8%, then X could be in top 6. But in the absence of that information, Insufficient.

Combining A and B,

56% paid by top 4. Thus remaining 2 have to pay 11.8. X is not necessary to be in 5th or 6th spot with 4.8% because there can be two countries with 5.9% each, in which case X can be 7th (or lower). At the same time, the 5th can be something like 7% in which case X can be the 6th.
Thus insufficient.

Hence E.

Will go with E too.

1) Top 4 contributors contribute 56%. But doesnot talk about X. Insuf
2) X = (4.8/100)*1.6B = .08B We don't know anything else. Insuff

Both:
69% of 1.6 B is 1.1 B, 56% of 1.6B is .89B and X contribution is .08B. We still cannot say whether X is in the other two countries.

Hence E
